vSAN Cluster Shutdown and Restart SOP

Objective

To safely shutdown and restart a vSAN cluster while ensuring data integrity and minimal downtime.

1.0 Preparation

* Verify all necessary personnel are available and informed.
* Ensure access to vSphere Client or Web Client.
* Document current cluster status and configuration.

2.0 Shutdown Procedure

1. Evacuate Virtual Machines: Migrate VMs off vSAN datastore to other datastores.
2. Disable vSAN Services: Access vSphere interface and disable vSAN services.
3. Put Hosts into Maintenance Mode: Place each host in the cluster into maintenance mode.
4. Verify Maintenance Mode: Confirm all VMs are evacuated and no vSAN objects remain.
5. Shutdown Hosts: Gracefully shutdown each host using vSphere interface.
6. Power Off Storage Devices and Networking Equipment: If applicable, follow manufacturer instructions to power off external storage and networking equipment.

3.0 Restart Procedure

1. Power On Networking Equipment and Storage Devices: If powered off, bring networking and storage devices online first.
2. Power On Hosts: Start hosts in the cluster one by one.
3. Verify Host Connectivity: Ensure hosts can connect to each other and external devices.
4. Verify Data Integrity: Check vSAN datastore and VM status for any issues.
5. Start vSAN Services: Enable vSAN services on each host.
6. Monitor Cluster Health: Run health checks and diagnostics to identify any issues.
7. Document Restart Details: Note any observations or actions taken during restart for future reference.

4.0 Completion

* Confirm successful restart of vSAN cluster.
* Document completion of shutdown and restart procedures.
* Notify relevant stakeholders of cluster status and availability.

5.0 References

* VMware documentation and best practices.
* Manufacturer instructions for storage and networking equipment.
